dotPeek: free .NET decompiler from JetBrains, the makers of ReSharper, dotTrace, and dotCover for .NET developers, as well as a family of IDEs for Java, Ruby, Python, PHP, and other languages, plus team development tools: TeamCity and YouTrack.

dotPeek goes public for the first time on Tuesday, May 10, as JetBrains open an Early Access Program that implies regular publishing of pre-release builds.
